new gears!!!!!
Just left the Mi. state fairgrounds swap meet. I picked up a rear end pumpkin complete with 3.73 gears for $150. I thought that the Vette only came with 3.70, but the seller stated them as 3.73. Either way, we turned it and the ratio was about 3 and 3/4 turns to 1, so I didn't get taken. It also seemed to turn pretty smoothly. Haven't decided what I'm going to do with the 3.36's. I may keep them for long trips and just swap the two pumpkins when the need arises. They should complement my stroker very well!

Re: new gears!!!!! (randy72)
I don't know if this is correct, but I hear alot of 80-82 guys talking about 3.73 gears and pre-79 guys talking about 3.70 gears. Is it possible that you got a 80-82 rear?

I'm with Nunus on this one. 
I too thought that it was the 80-82 crowd that used 3.73 ratios and the 63-79 guys were left with 3.70's :confused: . If you got the whole rear differential, you should measure and compare the spring mounting pad width.

Re: new gears!!!!! (SmokedTires)
The 3.70 was the vette gear. 3.73 were a popular Z28 gear on the late 70's camaros, plus aftermarket 3.73 ratios are aval. I have heard a lot of guys quote 3.73's not knowing that 3.70 was the gear. I don't think it will make much difference between the two. Same as comparing 4.11's vs 4.10's, though I'm not sure if the 4.10 was a 12bolt?

Re: new gears!!!!! (gtr1999)
I thought 3.70 was what was available for the Vette. This rear came out of a 65. When I clean it up before the install, I'll pull the rear cover and count the teeth.
